Disavow nothing - that was a bug in the compiler:
(this is 8.4.4)
(Tcl) 49 % if [puts A;expr 1] {puts 1} elseif [puts B;expr 2] {puts 2}
A
B
1
and in fact you could see this when avoiding the compiler in 8.3:
tellar [~] 91 > tclsh8.3
% if [puts A;expr 1] {puts 1} elseif [puts B;expr 2] {puts 2}
A
1
% eval {if [puts A;expr 1] {puts 1} elseif [puts B;expr 2] {puts 2}}
A
B
1
